the tag team

"For decades, in fact, Israel and Saudi Arabia—perhaps America’s two chief allies in the Middle East—have worked as a sort of "tag team" in regional affairs, agreeing to disagree (mostly) on the Palestinian issue but collaborating on many other subjects. During the Cold War, for instance, Israel and Saudi Arabia were unspoken allies against President Gamal Abdul Nasser of Egypt, and when Egypt and Saudi Arabia fought a proxy war in Yemen in the 1960s, Israel covertly aided Saudi Arabia."
